Summary: This study investigated the influence of different LED spectra on the performance of juvenile turbot. It was found that blue spectrum resulted in the best growth performance, antioxidative activity, and pathogen resistance, while red and orange spectrum led to growth retardation and decreased antioxidative activity and pathogen resistance. Therefore, blue spectrum is recommended for rearing juvenile turbot in aquaculture systems to improve fish welfare.

Summary: This study investigated the effects of fish protein hydrolysate (FPH) on intestinal microbiota and health of turbot fish. The results showed that an appropriate level of FPH improved growth performance, alleviated structural damage to the intestine caused by plant protein, and regulated immune-related inflammatory factors. Additionally, moderate levels of FPH in diets modulated the abundance of potentially probiotic and pathogenic bacteria in the intestine.

Summary: Juvenile turbots fed with diets containing 16% carbohydrate and 1.5 mg/kg biotin exhibited the best growth performance and glucose metabolism. Biotin decreased postprandial plasma glucose levels regardless of carbohydrate levels, indicating its potential in improving glucose regulation in juvenile turbot.

Summary: The study on genetic effects of inbreeding on growth trajectories in turbot revealed that inbreeding had a larger impact on body length compared to body weight and body width. The genetic effects were not linear with increasing inbreeding degrees and varied depending on the age of the fish. Additionally, there were low genetic correlations between growth traits in early growth days and later growth days.

Summary: A 10-week feeding trial was conducted to determine the optimal dietary methionine requirement of sub-adult turbot. The results showed that fish growth significantly increased with increasing dietary methionine levels up to 1.82% and then plateaued. Adequate dietary methionine improved protein and lipid levels in the whole body and liver. It also increased the content of methionine and other amino acids in the hepatic free amino acid pool and affected the expression of genes involved in lipid metabolism.

Summary: In turbot, fish protein hydrolysate (FPH) mainly modulates the expression of MSTNb in the muscle, while MSTNa is only affected in the early stage of refeeding. Optimal levels of FPH in diets may regulate MSTNb more rapidly to initiate compensatory growth.

Summary: Temperature tolerance is an important economic and evolutionary trait in fish, and genome-wide selection using QTLs affecting Upper temperature tolerance may be a genetic improvement alternative. This study mapped QTLs, annotated gene sequences, and identified markers that could help select thermal-tolerant turbot breeds, providing valuable genomic resources for understanding genetic mechanisms regulating thermal stress and potentially improving turbot performance through MAS programs.

Summary: This study investigated the effect of triploidy on the growth, carcass yield, and fatty acid composition of Black Sea turbot. The results showed that there was no significant difference in growth and carcass yield between diploid and triploid turbot. The fatty acid composition varied with ploidy status, with triploid turbot having higher PUFA n-3 content and diploid turbot having higher PUFA n-6 content.

Summary: The effects of dietary supplementation with Sophora flavescens root extract (SFE) on growth, antioxidant capacity, immune status, and disease resistance in turbot were investigated. The results showed that supplementation with 0.1% and 0.2% SFE significantly improved the growth performance and antioxidant activity of turbot. SFE also increased the survival rate of turbot against Edwardsiella tarda challenge. These findings suggest that SFE could be a potential feed additive for turbot.

Summary: The study found that the growth of tiger puffer was not affected by diets containing 12.6-55.9 g kg(-1) leucine. An excess of dietary leucine, isoleucine, or valine possibly resulted in antagonism between BCAAs, showing that excessive intake of one BCAA may lead to antagonistic effects when the other two BCAAs met the requirements for tiger puffer.

Summary: This study investigated the sex difference in fatty acid composition of six wild marine fish species, revealing universal existence of sex difference in FA composition, particularly in gonad, intestine and liver. The sex difference was highly dependent on fish species, with DHA, 18:1n-9, 16:1n-7, 16:0 and EPA appearing to be the top FAs differentially abundant between sexes.

Summary: The study investigated the response of intestinal microbiota to fish oil finishing (FOF) strategy in tiger puffer. It was found that terrestrially sourced oils impaired intestinal function during the growing-out period, but this was significantly recovered by re-feeding with fish oil-based diet. The 16S rDNA sequencing analysis showed improved bacterial community similarity after FOF, indicating the important role of intestinal microbiota in the recovery process.

Summary: The booming fish farming industry has led to a shortage of fish oil supply, resulting in the use of alternative oils in fish feeds and a reduction of long-chain polyunsaturated fatty acids (LC-PUFAs) in fish products. This study explored the efficacy of an fish oil-finishing strategy to restore muscle quality in farmed tiger puffer. The strategy successfully recovered LC-PUFA content and volatile flavor compounds in the fish after being fed poultry oil-based diets.

Summary: The objective of this study was to investigate the effect of graded levels of tryptophan on the growth, cannibalism, and 5-hydroxytryptpamine metabolism in pufferfish. The results showed that excessive tryptophan could mitigate cannibalistic behavior and promote the growth of pufferfish, possibly by affecting the metabolism of 5-TH.

Summary: A 12-week feeding experiment was conducted to evaluate the effects of replacing fish oil (FO) with beef tallow (BT) on the fatty acid composition of farmed tiger puffer (Takifugu rubripes). The results showed that dietary BT inclusion reduced the contents of long-chain polyunsaturated fatty acids (LC-PUFA) in both the muscle and liver of the experimental fish, and the liver displayed a more drastic decrease than the muscle. However, alternate feeding between FO and BT-based diets resulted in a higher LC-PUFA content than the standard direct replacement.

Summary: The effects of imbalanced dietary BCAAs, specifically Leu, on the growth and metabolism of turbot were investigated in this study. The results showed that turbot exhibited high plasticity to an excess of any particular BCAA in terms of growth. Excessive intake of a specific BCAA increased its concentration in the plasma, muscles, and liver, and also influenced intestinal amino acid absorption and BCAA catabolism.
